appertains to make and use the same.

This 1nvent1on relates to incandescent burner .fixtures and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a fixture adapted to support and retain a mantle of substantially V-shape in cross section and circular or ellliptical in general outline, and means for supplying the same with a mixture of gas and air to be ignited and consumed at the mantle and producing a large and brilliant light with the consumption of a minimum quantity of the as. b A further object of the invention is to -provide in a fixture of the'character stated means for conducting air from the'exterior and in a heated condltion to theinterlor of the annular mantle at the time that the mixwhich regulatingmeans is located beyond oroutside of the heating Zone of the burner.

proper, and may be readily adjusted while the burner is ignited.

' A still further object ofthe invention is to provide new and novel gas controlling means in the form of a valve having a bypath adapted to be connected with the pilot light or burner of the incandescent fixture.

able metal having a passage-way 2 adapted to be connected with a service pipe A by-path 4 connects at one end with the pas sageway 2 and extends under a'hood portion 5 which is mounted upon the body 1. 11 screw 6 is threaded in the hood 5 and its lower portion projects into the by-path 1 andthe screw may be adjusted in the hood to increase or diminish the transverse sectional area of thepassageway through the said by-path. One end of a pipe 7 is connected. with the hood 5'at the outlet end of the by-path 4 and the said pipe extends down and enters the burner fixture and is provided with atip 8 which is located in the body of the burner and at which point the gas may be ignited and serve'as a pilot light for the fixture. H

A valve 9 is rotatably mounted in the body 1 and is provided with a port 10 which may be moved into alinement with the passageway 2 or may be moved transversely thereof in a usual manner. A bar 11 is mounted upon the stem of the valve 9 and chains 12 may hang pendant from theends of the bar and may be used for swinging the bar when it is desiredto turn the valve 9 in thebody l to shut off the flow of gas to the body and the passageway 2orto permit the gas to flow through the said passageway in a. usual manner; g

A nipple 13 isscrew threaded in the body 1 at the delivery end of the passageway 2 and the lower portion of the said nipple is diametrically enlarged andretains a needle 14, the inner portion of which is vertically or downwardly disposed; The nipple 13 is provided betweentheends of its lower enwhich receives the lower portion of the" larged portion with an externally located I needle 14. The lower end of the needle is pointed and the aperture 20 is funnel shaped and by turning the disk 19 the col lar 18 is moved with relation to the enlarged portion of the nipple 13 and consequently the transverse sectional area of the space between the walls of the aperture 20 and the exterior surface of the pointed end of the needle 14 may be increased or diminished and consequently the flow of the gas, or mixture of air and gas through the opening 20 of the disk 19 may be regulated.

A two piece cylindrical casing 21 is screw threaded at its upper end in the flange 17 and it is provided with opposed openings 23. Through the openings 23 the fingers of an operator may be inserted to grasp the '21 and is provided at its edge with an internally threaded annular flange 26 which is screwed into engagement with the lower portion of the casing 21. A nipple 27 passes through the center of the disk 25 and is provided at its upper end with a flange 28 which bears at its upper surface against the lower edge of the casing 21 and at its lower side against the disk 25. The nipple 27 is provided with an interiorly located strainer 29 which may be of wire mesh material or any other suitable material., A pipe 30 is connected by means of a' union nut 31 withthe lower end of the nipple 27. The pipe 30 is angular in side elevation, and its lower end connects with a boss 32 provided at the center of a distributing casing 33. The casing 33 is provided at its sides with radially disposed braces orstruts 34 which are connected at their outer ends with the burner casing 35 in an appropriate manner. The casing 33 is provided at its lower side with spaced inner and outer flanges 36 which in turn are provided with L-shaped slots 37. Pipes 38 pass through the intermediate portion of the casing 33 at points beyond the sides of the nipple and are open at their upper and lower ends.

The burner proper comprises an inner ring 40 provided at its side with lugs 41 adapted to enter the L-shaped slots 37 of the inner flange 36 of the casing 33. The inner ring 40 is of heat resisting material, and bears at its sides against the inner flange 36 at the lower edge thereof. The ring 40 is provided at its inner side with recesses 42 havinglugs 43" located therein and the lugs are provided at their upper sides and at points between their ends with notches 44. An outer ring 45 is adapted to be povided at its inner side with lugs 46 adapted to enter the L-shaped slots 37 in the outer flange 36 of the casing 33. The inner surface of the ring 45 bears against the outer surface of the outer flange 36 and extends beyond the lower edge thereof. The ring 45 is provided at its outer side with recesses I 42 having lugs 46 located therein, the said lugs being provided at their upper sides and at points between their ends with notches 44.

The mantle frame comprises an inner ring 47 and an outer ring 48. These rings are held in concentric position with relation to each other by means of braces 49 and the rings 47 and 48 are provided at their outer surfaces with grooves 50 adapted to receive the edge portions of the mantle 51 and securing wires 52 in the usual manner. The braces 49 are provided at their ends with upwardly disposed arms 53 having at their upper ends cross heads 54. The inner ends of the heads 54 are adapted to enter the recesses 42 and 42' when the mantle frame is applied to the rings 40 and 45, and when the mantle frame is turned the inner ends of the heads 54 rest in the notches 44 and 44 of the blocks 43 and 43 of the supporting rings.

In operation the mixture of air and gas passes through the pipe 30 and enters the casing 33 where it is distributed and passes through the space between the flanges 36 and enters the space between the sides of the mantle 51, where it is ignited and burned and produces incandescence in the mantle in the usual manner. At the same time air from the exterior is drawn down through the pipes 38 and while passing through the said pipes is heated by radiation of the heat from the mantle and flame. This heated air supplies warm oxygen to the inner portions of the mantle and to the flame which is burning at the lower edges of therings 40 and 45. Inasmuch as the regulating device for controlling the relative quantities of the air and gas constituting the mixture is lo cated at one side of the body 35, the said regulating device is not in the heating zone of the burner, and consequently it may be manipulated while the burner is lighted to regulate the proportion of the air and gas which constitutes the mixture.

Having described the invention what is claimed is: I

1. A burner device having a casing; a burner in separable sections detachably supported from the casing, a frame extending across the sections and engageable therewith and detachably supported from the sections on opposite sides of the burner, and a mantle supported by the frame.

2. Aburner 'device having a casing, a burner in separable sections detachably supported from the casing, said sections having recesses, a mantle having substantially non-separable parts and a frame to support the mantle disposed on opposite sides of the burner and suspended in the recesses.

3. A burner device having a casing, a burner in separable sections detachably supported therefrom, said sections each having a recess, a frame having rings'on opposite sides ofthe burner, connecting means for the rings extending across the sections, arms extending from the rings having lugs to enter said recesses, said rings having grooves, a mantle, and means to secure the mantle engageable in said grooves.

4. A burner device having a fuel mixture regulator comprising a nipple, a valve needle mounted thereby, a valve member screwed to the nipple having an opening to receive the needle, a flange extending from the nipple, a second nipple having a flange extending therefrom, a tube intermediate and positioned by the flange, and closures overlapping the flanges and screwed to the exterior of the tube.

In testimony whereof I affix my signature in presence of two Witnesses.
